I will be even more impressed if you put it back together.
Right on dude! let do the reverse engineering and manufacture your own L-lens from it...
Just imagined if I have the 24-70mm f/2.8 lens as my pencils holder. Way too cool!!!

Now that I've done it, I think I could've reassembled it with a replacement part, but only if I had kept thorough track of what went where. Also, I totally stripped at least 3 screws in the process. Overall, the inner workings were a bit more complex than I expected, but it was a nice linear process taking it apart.
